7 signs your child may have a food intolerance
4. Eczema or itchy skin rash
Possible culprit: Reaction to a combination of gluten, casein (in dairy products), eggs and what Dorfman calls “extended” citrus (oranges, grapefruit, tangerines, lemons, strawberries and pineapple).
Action plan: Ask an allergist to conduct an IgE radioallergosorbent (RAST) blood test on your child. Because an itchy rash suggests a histamine response, blood tests can be more accurate here than they can be in detecting food sensitivities.
